🌬 Systemair RVK Fans Guide & Product Information

🌱 Professional Ventilation for Grow Rooms & Hydroponics

The Systemair RVK Fan range is one of the most widely used and respected inline extractor fan systems in the hydroponics industry. Designed for powerful grow room extraction, RVK fans combine high airflow performance, strong static pressure capabilities, and reliable long-term operation for professional ventilation systems.

Whether you are ventilating a grow tent, medium-sized grow room, or larger hydroponic environment, the RVK range provides efficient airflow capable of handling carbon filters, acoustic ducting, and longer extraction runs without major airflow loss.

Strong extraction is essential for controlling temperatures, humidity, fresh air exchange, and odour management inside indoor growing environments. The RVK range is specifically designed to maintain stable environmental conditions while delivering reliable airflow performance.

• ✔ Professional grow room extraction performance
• ✔ Powerful airflow for hydroponic ventilation systems
• ✔ Excellent pressure handling for carbon filters
• ✔ Reliable long-term extraction performance

🌀 Mixed-Flow Fan Technology

Systemair RVK Fans use advanced mixed-flow impeller technology designed to combine the airflow advantages of axial fans with the pressure-handling capabilities of centrifugal systems.

This allows RVK fans to maintain strong airflow even when connected to carbon filters, silencers, and longer ducting systems where weaker fans may lose efficiency.

Mixed-flow extraction systems are highly regarded within hydroponics because they offer:

• ✔ High airflow performance
• ✔ Excellent static pressure capabilities
• ✔ Improved efficiency with carbon filters
• ✔ Reliable airflow through longer duct runs

⚡ A1 Low Power & L1 High Power Configurations

The Systemair RVK range available from Acorn Horticulture includes both A1 Low Power and L1 High Power configurations depending on the grow room ventilation requirements.

The A1 models provide efficient extraction for smaller and medium-sized grow environments, while the L1 High Power versions deliver increased airflow performance for larger grow rooms and higher heat loads.

Available configurations include:

• ✔ 4″ / 100mm – A1 Low Power
• ✔ 5″ / 125mm – A1 Low Power
• ✔ 6″ / 150mm – A1 Low Power
• ✔ 6″ / 150mm – L1 High Power
• ✔ 8″ / 200mm – A1 Low Power
• ✔ 8″ / 200mm – L1 High Power
• ✔ 10″ / 250mm – A1 Low Power
• ✔ 10″ / 250mm – L1 High Power
• ✔ 12″ / 315mm – A1 Low Power

The smaller 4″, 5″, and 6″ models are ideal for grow tents and compact grow spaces, while the larger 8″, 10″, and 12″ versions are suitable for larger grow rooms and professional extraction systems.

🔧 Speed Controller Compatibility

Systemair RVK Fans are compatible with fan speed controllers and environmental controllers, allowing growers to adjust airflow depending on environmental conditions.

Adjustable airflow provides greater control over:

• ✔ Grow room temperatures
• ✔ Humidity levels
• ✔ Noise reduction during cooler periods
• ✔ Environmental stability

🌬 Benefits for Indoor Growing

A high-quality extraction system is essential for maintaining healthy grow room conditions. The RVK range helps remove excess heat, stale air, and humidity while improving fresh airflow and carbon filter efficiency.

Proper extraction helps:

• ✔ Control grow room temperatures
• ✔ Reduce humidity and condensation
• ✔ Improve fresh air and CO₂ exchange
• ✔ Improve carbon filter odour control
• ✔ Support healthier plant growth
